Associated production of the scalars and new gauge bosons from a little Higgs model at the LHC

Abstract

The littlest Higgs model with T-parity ($LHT$ model) predicts the existence of the T-odd scalars ($\ddot{I}{•}^{\pm }$, $\ddot{I}{•}^0$, and $\ddot{I}{•}^p$). We consider production of these new particles associated with T-odd gauge bosons at the $LHC$. We find that the partonic process $q\overline{q^{\prime }}\to \ddot{I}{•}^{+}{B}_H$ can generate a number of the characteristic signal events with a charged lepton and large missing energy at the $LHC$.
